Abstract

The function of non-metallic inclusion activity in the nucleation and propagation of corrosive damage in wheel steel is investigated, the consequent set of inclusions according to their harmful effect is established, and the extent of non-metallic inclusion effect on low-cycle durability of wheel steel is defined. The function of inclusive-matrix interphase boundaries in wheel steel microchemical heterogeneity in the propagation of adsorptive and corrosive processes during wheel operation is investigated.
